Swift中NSWorkspace.OpenConfiguration()配置不生效问题如何解决？

• 代码中先调用了无配置的workspace.open(bundleURL)方法，这个调用会直接正常启动、激活并显示Safari，后续带配置的openApplication执行时，Safari已经处于运行状态，而NSWorkspace.OpenConfiguration的activates、hides参数仅对新启动的应用进程生效，对已经运行的应用不会触发状态变更。
• 重复调用启动方法时，系统默认会触发已运行应用的激活逻辑，反而抵消了你的配置效果。

let workspace = NSWorkspace.shared
if let bundleURL = workspace.urlForApplication(withBundleIdentifier: "com.apple.Safari"){
   let conf = NSWorkspace.OpenConfiguration()
   conf.activates = false
   conf.hides = true
   workspace.openApplication(at: bundleURL, configuration: conf){ (app, err) in
       print(app as Any)
       print(err as Any)
   }
}

如果需要兼容Safari已经在后台运行的场景，可以在回调中额外添加隐藏逻辑：

workspace.openApplication(at: bundleURL, configuration: conf){ (app, err) in
    if let app = app {
        // 针对已运行的应用主动触发隐藏
        app.hide()
    }
    print(app as Any)
    print(err as Any)
}
